I know of a Lorenzo Douw son of Adam, son of Henry Adam (1766-1828). Adam (ABT. 1788-1839) M. Magdalena (Lenah) Quackenbush. Henry Adam also had Peter (1892), Douw Henry and Henry Douw (twins 1809), Adam H. (1799-1852), and this other Adam, the one that had Lorenzo Douw. I don't have dates on Lorenzo. I hope that is of some help.
